Could someone explain how Circuit switching and packet switching works?
‘Circuit switching’ implies that the system has a circuit which is dedicated to the transaction for the length of the transaction, and from one party to the other party–whether the parties are actually actively exchanging information all the time or not. Packet switching aggregates the information at some central office, and then has a single link (which is shared) to the other central office. If neither party is using the link at some time, then neither party occupies bandwidth on the shared link–which means it’s available for somebody else.
